Closes#261
## Summary
- improve startup remote URL selection when the server binds to
`0.0.0.0`
- print additional reachable remote URLs instead of advertising only the
first external address
- add targeted tests for address ordering and advertisability behavior
## Problem
When CodeNomad was started with `--host 0.0.0.0`, the CLI chose the
first external IPv4 address it discovered and displayed only that one as
the remote URL.
On Windows machines with WSL, Hyper-V, Docker, or other virtual
adapters, that often surfaced a virtual `172.x.x.x` address even though
a more useful LAN address such as `192.168.x.x` was also reachable and
usable from other devices.
That made remote access look broken or confusing even though the server
itself was accessible.
## What changed
- reuse the resolved network-address list for both:
- primary remote URL selection
- startup logging of additional reachable URLs
- choose the primary remote URL from the **advertisable** external
addresses instead of any external address
- print `Other Accessible URLs` when multiple useful remote URLs are
available
- avoid hard-coding a preference like `192.168 > 10 > 172`
- suppress link-local `169.254.*` addresses from user-facing advertised
URLs
- add tests covering:
- stable ordering across RFC1918 address ranges
- link-local addresses being non-advertisable
- link-local-first discovery not stealing the primary LAN URL
## Why this approach
This keeps address derivation in the network-address resolver layer and
limits `index.ts` to startup wiring and presentation.
It also fixes the misleading terminal output without redesigning binding
behavior, TLS behavior, or the server API contract.
## Validation
- `npm run typecheck --workspace @neuralnomads/codenomad`
- `npx tsx --test
'.\\src\\server\\__tests__\\network-addresses.test.ts'`
## Notes
- this change is intentionally focused on selection and presentation of
reachable addresses
- it does not attempt a broader virtual-adapter classification policy
beyond suppressing clearly low-value link-local addresses in user-facing
output
